- Little instructional video to show how I mix up ferric chloride for etching.
Check out / parkerknivesaustralia , this was Adams Recipe, and the steel cam from Barry at / gardnerknives
I'm not totally convinced with the second part, so I will do a follow up video when I find a better option.

Brilliant video. About to etch my first knife next weekend and this was the clearest simple video. Thanks mate
Glad it helped, thanks for watching.
I really enjoyed your video, especially when I realised you were using an aluminium saucepan to mix the caustic solution in! 🤣
at least I got to learn something else new.
First of all I wanna say your voice is awesome tbh, and also great video👍🏻👍🏻
Thankyou.
Great lesson here, thanks.
Perfect help!! Thank you much!
Good information. Have a blessed day!
Same to you
Well now I want to etch something❤️🔥
Hello sir! What is the concentration of the FeCl3 you are using? I could find only 40% here, asking so I will know the right amount I should mix for my etching. Thank you!
Good stuff
Thanks Adams
I live in Vietnam . Many thanks for the video.
My pleasure, Glad it was useful.
Good stuff. I think I need to dilute my fecl. Also thanks for the cleaning tip. Windex works well to neutralize it as well
Windex would be a lot easier than caustic soda. Ill try that next time.
Thanks Drew.
You made the acid really weak, and yet used the most extreme base you could find. A little baking soda would have neutralized the acid, even at full strength.
Thank you very much!
You're welcome!
Soon and I just made about 1250ml of b ferric chloride. We're going for a very dark etch. We're going to dilute it 2:1 with hydrogen peroxide. Thanks for showing the etch.
Don't confuse stronger mix with being darker. The stronger it is, the more aggressive it is at pitting the metal.
If you want darker, try a really (really, really) strong mix of instant coffee and soak in that overnight after the ferric.
@@FirePantsFabrication - I bought ferric chloride now. Two 16oz bottles of it.
Is there anything to my hunch that maybe my heat treat was not even?
Never mix caustic with aluminium, it reacts. That's why the saucepan was bubbling
Live and learn
gday Mate. I ordered ferric chloride from Gameco Artisan Supplies and it came in a powder. any ideas on how I mix it?
unfortunately not. I've only ordered the liquid. Perhaps email the guys at Element14, they sell the same stuff as gameco (that's probably where it comes from) and should be able to advise.
capped pvc piping is great for the solution storage and etching blades.
If you leave it with cap on and then open later does it create any dangerous vapor for next time i open the cap or is it safe to reuse?
do you have a website selling striking anvils
Yes I do, www.firepantsfab.com.au
We have a few options on there.
Is the black pvc pipe suitable for storing ferric chloride?
I'm not aware of black PVC, but i know lots of people use the white PVC for storage.
I’m trying to put a copper finish on my knife but every time I go to wipe off it comes off. Any advice?
Sort of.
You need to look at electroplating to get a proper bond.
I only have the ferric cloride powder,,somebody cant tell me how to mix it,,,so i can etch my damascus knife
How’s that Aluminum pan doing? 😂
It's still alive, slightly pitted.
From my etching eperience the best material for really sharp and homogeneus etching was by far caustic soda. The ferric chloride etch always ended up looking bumpy on a larger scale and if you are using ferric chloride that was used for pcb etching it will form a "rust" crust on the etch (at least thats what happened with alluminum).
Can you elaborate more on your caustic soda etching? What types of materials, do you just use it out of the bottle, how long?
@@6666todor You can buy caustic soda flakes at a local supermarket for your etching solution just mix it up with water be careful tho it generates a lot of heat, for your design you can use what people usually call a toner transfer method which is basically a reversed image printed with a laser printer, then you place the paper over the metal surface ad heat it up with a clothing iron, afterwards you will let it sit down until it cools down, then remove the paper very carefully you dont want to peel off any of the paint that will be deposited over the metal surface, cover all the parts that you dont want etched with plastic tape, apply the caustic soda with a pipette or brush and brush off the solution off the object every 5 minutes or so just so you know if everything is going ok, after that just clean it with water (I like to pour some vinegar over the surface just to be sure) if tou want to know moire about this tecnique you can search for "Acid etched pedal enclosure" on youtube
@@pedromartinazzo5036 Thank you! I'm familiar with other etching techniques, just haven't tried caustic, will do and see how it goes!
Which technique is more resistant over time on knives ?
@@RaduMichael The durability is dependant on the depth of the etch so I would say a 4 part Ferric Chloride 1 part Citric Acid would work the best because it will give you a deep etch, another thing you can try is to use this same solution but use old Ferric chloride that was used to etch copper such as in Pcb manufacturing, the reaction is much faster than with new Ferric chloride but the copper makes a crust over the aluminum so you have to clean it constantly which is why you add the citric acid to the solution
Have you ever tried cable Damascus steel to make knifes 😁👍🇮🇪👍
Not yet mate, I have some cable here, and a new forge. I need to give it a go.
Please, use safety glasses and acid resistant gloves. Good video amigo!
thankyou
Is it IRON 3 CHLORIDE?
yes, correct
It's look like the sospan made of aluminum? It's extensively react with caustic soda !
yep, I know that now.
Shut up nerd
and yeah Caustic soda will eat through Aluminium. Plastic is your friend for caustic as It also eats glass FYI.
Now I know. Thanks.
Caustic soda only eats glass when the temperature is kept very high for a long time. At room temperature it won't eat glassware.

Problem with etching a Chinese vg10 knife which is pretty much stainless steel Damascus
try Hydrochloric acid for etching stainless, but VG10 is not damascus.
The water/caustic add doesn’t matter. Sodium hydroxide is a base not an acid.
but its always a good idea to arrange additions so that it starts off weak or dilute just in case there is a splashback or spillage. Therefore adding chemicals to water means that you wont cover your hands and face with very concentrated solutions. Simple practical safe working method.
